Next, you need to find your windows driver for your wireless card. You need to find an archived version, not an executable.
After this is done, extract the .inf and .sys files and place them in the same directory.

then type:

$ sudo ndiswrapper -i drivername.inf
...
$ ndiswrapper -l

If the ndiswrapper -l call says something similar to: "driver present, hardware(or device) present" then you are ready for the next step. However, if it returns "driver present" then something went wrong.
